摘要
嵩县雷门沟钼矿为斑岩型钼矿床,控矿斑岩体岩性主要为正长花岗斑岩–斑状二长花岗岩。与控矿斑岩体上侵及冷凝有关的非构造裂隙强烈发育,这些裂隙规模虽小却是各种含矿脉体充填的场所且与构造作用无关,它直接控制着成矿金属矿物的赋存,充分反映了斑岩型矿床的裂隙系统特征。本文重点研究了雷门沟斑岩型钼矿床非构造裂隙的主要类型及控矿特点,为深入研究雷门沟钼矿成矿作用过程及矿床模型建立提供了新的思路。
Leimengou molybdenum deposit in Song County is a porphyry type molybdenum deposit. The ore-controlling porphyry body is mainly syenite-porphyry monzonite granite. The non-structural fractures related to the intrusion and condensation of ore-controlling porphyry bodies are strongly developed. Although these fractures are small in size, they are filled by various ore-bearing veins and are not related to tectonism. They also directly control the occurrence of metallogenetic metallic minerals. It fully reflects the characteristics of fracture system of porphyry deposit. In this paper, the main types and ore-controlling characteristics of non-structural fissures in the Leimengou porphyry molybdenum deposit are studied.
